netfilter: nf_tables: allow to fetch set elements when table has an owner

Browse Source 
[ Upstream commit 92f3e96d642f5e05b9dc710c06fedc669f1b4f00 ]

NFT_MSG_GETSETELEM returns -EPERM when fetching set elements that belong
to table that has an owner. This results in empty set/map listing from
userspace.
